The House of Quality(HOQ) is used in the development stage to identify important customer attributes and corresponding engineering characteristics. The importance of each customer attribute obtained in the HOQ affects to the quality of the final product or service. Traditionally, such importance is derived based on the assumption that customer satisfaction is linearly proportional to the product performance. In this paper, we propose a nonlinear function so as to relate the product performance with the customer satisfaction according to the Kano model. A performance goal is obtained by maximizing the total customer satisfaction under a cost constraint and the importance of each customer attribute is developed from the performance goal. Therefore, the proposed approach incorporates the Kano categories and the improvement cost in determining the importance of customer attributes.

Obtaining the accurate final importance of each customer attribute (CA) is very important in the house of quality(HOQ), because it is deployed to the quality of the final product or service through the quality function deployment(QFD). The final importance is often calculated by the multiplication of the relative importance rate and the competitive priority rate. Traditionally, the sample mean is used for estimating two rates but the dispersion is ignored. This paper proposes a new approach that incorporates statistical significance to consider the dispersion of rates in determining the final importance of CA. The approach is illustrated with a design of car door for each case of crisp and fuzzy numbers.

As the life style of modern people is gradually being more scientific, up-to-date and specialized, food habit and food culture are a measure of cultural level of a country. Studies on consumer behavioral model show that food habit is closely related to consumer preference, changing life pattern and increasing family income. The purpose of this study was, accordingly, to define the impact of menu characteristics on customer menu selection. For that purpose, some attempts were made: First, discuss the theories on Italian food and customer purchasing behavior as a standard of analysis. Second, find out if there are any differences in customer menu-selection factors in hotel Italian restaurant. Third, make an empirical analysis of menu-selection factors in hotel Italian restaurant to suggest in which direction it should move forward. Fourth, analyze the relationship of demographic characteristics to menu-selection factors.

The purpose of this study is to investigate the preference of Korean traditional food and kimchi among different age groups in order to find a way to increase kimchi consumption. For this study, data from 15 male respondents(5.2%) and 271 female respondents(94.8%) was used. Age distribution of total respondents were in their 20's(21.8%), 30's(32.7%), 40's(32.7%) and 50's(11.6%), which showed the rate of 40's was very high. Most of the groups showed similar rates over the question on "have to eat kimchi" and "don't need to eat kimchi", but the elders' preference was high while the youngers' was relatively low. Therefore, the preference of kimchi has a small gap between the age groups, but all of them like kimchi in general.
